3 Claims.

The invention pertains in general to twisting machines of the type inwhich paired threads to be wound upon power driven bobbins are suppliedfrom larger yarn masses or cheeses supported upon a creel; and it hasmore special reference to a novel spindle construction for sup portingthe cheeses on the creel.

It has heretofore been the practice to support the cheeses upon a creelequipped with slightly inclined spindles, each adapted to support a pairof cheeses with the adjacent ends of the cheese cores in frictionalengagement. With the spindles thus constructed, it has been necessary topull the threads from the paired cheeses in opposite directions due tothe fact that the frictional bearing engagement between the abuttingends of the cheese cores is sufficient to cause a driving action ofone,of the cheeses upon the other, particularly in the case of cheesesof diflerent diameters. On the other hand, rotation of the pairedcheeses in opposite directions is objectionable because of the drag onthe threads incident to the frictional engagement between the cheeses,and also because the mounting of the cheeses on the spindles so as torequire the yarn strands or threads to be pulled off in oppositedirections is inconvenient and time consunning.

With the foregoing in view, the object of my invention is to provide anovel spindle construction which eliminates the frictional bearingengagement between the cores of the two cheeses mounted thereon andwhich, therefore, permits the cheeses to be so mounted that the threadsare pulled therefrom in the same direction.

Figure l is the front view of a twisting machine upon which the improvedspindle is used;

Figure 2 is an end view of the machine shown in Figure 1;

Figure 3 is a cross sectional view of one of the spindles showing a pairof cheeses mounted thereon;

, Figure 4: is an elevation of the improved spindle and Figure 5 is anend view of a portion of the spindle showing the shoulder and eccentrictip.

In Figs. 1 and 2 of the drawings, I have shown for purposes ofillustration a twisting machine generally designated 1 having a series apower driven bobbins B, to each of which paired threads are suppliedfrom cheeses C mounted upon a creel generally designated 8, the pairedthreads being guided and controlled in a conventional manner. As shown.the threads pass downwardly through guides 8 and thence consecutivelybeas with the Burlingame, Pawtucket, R. 1., assignor Rockford, 111., a

tween rollers Ill and thread guides II to the ring rail l2.

The cheeses C are supported upon the creel 8 by means of fixed spindlesl3 slightly inclined from the horizontal, in the conventional manner. Inaccordance with my invention, each spindle is constructed to support apair of cheeses in axially spaced relation in a manner such as to avoidany frictional engagement between the two cheeses while permitting offree and easy placement and removal of the cheeses on the spindle. Asshown, each cheese has a central core M of wood, and the spindle isespecially shaped to provide an inner portion l3a providing a bearingfor the core of the innermost cheese, and an outer portion l3b providinga bearing for the core of the outermost cheese.

The inner portion l3a of the spindle is made of a diameter substantiallycorresponding to that of the internal diameter of the central bore ofthe core, but the outer end portion of the spindle is cut away at itsupper side so as to form a bearing surface offset downwardly withrespect to the upper surface of the portion l3a. Thus, the upper surfaceof the outer portion l3b is in effect disposed eccentrically withrespect to the corresponding surface of the inner end portion l3a.Between the two bearing surfaces of the spindle is formed a shoulder l5for engagement by an annular bearing surface It at the inner end of thecheese core. As herein shown, the surface It is formed by the bottom ofa socket ll providing, in the case of the innermost cheese, clearancefor the spindle fastening means. This means may comprise a hexagonalportion is and a. threaded stem 19 for insertion through a hole in thecreel frame, the spindle being secured in position vby means of a nut20. Preferably, the outer end of the hexagonal portion I8 is rounded toprovide a bearing shoulder I8a for engagement by the bearing surface Itof the core.

It will be seen that through the provision of two bearing surfacesofiset transversely with respect to each other, together with thebearing shoulders l5 and l8a, the two cheese cores are maintained inaxially spaced relation free of frictional engagement between the cores.Accordingly, it is possible to mount the cheeses on the creel so as topermit the threads to be pulled from adjacent pairs in the samedirection. At the same time, the construction and arrangement employeddoes not in any way interfere free and easy placement or removal of 3the cheeses with respect to their supporting spindles.

I claim as my invention:

1. In a twisting machine or the like having means for rotatablysupporting a plurality of bobbins to be wound, means for supplying yarnto the bobbins comprising a creel having a pinrality of inclinedspindles each adapted to support a pair of cheeses and providing bearingsurfaces transversely offset with respect to each other and terminatingat their inner ends in bearing shoulders for engagement by the cheesecores, said shouldersbeing spaced apart axially of the spindle so as tomaintain the cores in axially spaced relation.

2. A spindle for supporting a pair of cheeses for rotation on axesinclined slightly from the horizontal, comprising inner and outerportions for engagement by the cores of the respective cheeses. theouter portion of the spindle having its upper portion cut away so as tobe offset downwardly from the corresponding surface of the innerportion, and a bearing shoulder at the inner end of said outer portionfor engagement by the core oi the outermost cheese whereby the two coresare held in axially spaced relation.

3. A spindle for supporting a pair of cheeses for rotation on axesinclined slightly from the horizontal, comprising inner and outerportions for engagement by the cores of the respective cheeses, lheouter portion of the spindle having a bearing surface oflset downwardlyfrom the bearing surface of the inner portion and terminating at itsinner end in a shoulder for engagement by the core of the outermostcheese and means at the inner end of the spindle providing a bearingshoulder for the innermost cheese.
